Commercial kitchen flooring decisions surface at a specific moment: a tile floor with failing grout lines is flagged on a health inspection, a renovation or new build is underway, or a kitchen manager is tired of scrubbing grout that still looks dirty after cleaning. At that point, the facility owner or manager has to choose between re-tiling and switching to a seamless resinous system such as epoxy or urethane cement. Food Code 6-201.11 sets a smooth and easily cleanable expectation for floors, and whether a given tile or resinous installation meets it is determined by the local regulatory authority. Tile and resinous floors differ in how they are installed, how they are repaired, and how they behave around drains, steam, and hot washdown. This guide walks through what each system is, how they compare on cleanability and seams, how they handle wet and hot conditions, how they're built at drains and cove bases, and what downtime and repair look like. Use it alongside the Colorado Commercial Kitchens & Restaurants hub and the cost calculator when scoping a project.
Tile is a modular flooring of ceramic or porcelain units with grout filling the joints between them. Epoxy and urethane cement are resinous systems: liquid or trowel-applied resins that cure in place to form a continuous, seamless floor without joints or grout lines. Thickness varies by product: Tnemec N222 epoxy mortar is 3/16 to 1/4 inch, Carboline Shock-Crete HD is 1/4 to 1/2 inch, and Sika Ucrete RG29 NA cove mortar is 1/8 to 1/4 inch.
| System | Attribute | Value |
|---|---|---|
| Tnemec Series N222 epoxy mortar | Install thickness | 3/16 to 1/4 inch, min 1/8 inch, max 1 inch (per Tnemec data sheet) |
| Carboline Shock-Crete HD urethane cement mortar | Recommended thickness | 1/4 to 1/2 inch (6 to 13 mm), per Carboline data sheet |
| Sikafloor-20 NA PurCem urethane cement | Stated service temperature | -40 °F up to 248 °F, per Sika Canada data sheet |

What to put in the written scope:
A tile floor has a cleanable field surface but also has grout joints between units; a seamless resinous floor has no joints in the field. The FDA Food Code 2026 (6-201.11) describes the general expectation that food establishment floors, walls, and ceilings be smooth and easily cleanable, except where anti-slip coverings or applications are used for safety. Colorado's retail food establishment rule, 6 CCR 1010-2, incorporates the Food Code 2022 edition (as in effect January 18, 2023) rather than the 2026 edition, and treats facility design and construction as within its scope; it is enforced by the state and local health authorities that act as the regulatory authority under that rule.

Kitchens generate hot washdown water, steam, grease, and organic acids. Sherwin-Williams' tech tip on thermal shock resistance defines it as a solid's ability to withstand sudden heating or cooling changes, and illustrates the concept with an example of a food-processing floor at 35 °F washed with 185 °F water, a 150-degree difference; this is presented as an explanatory example, not a specification limit. Sika's data sheet for its Sikafloor-20 NA PurCem urethane cement states the product keeps its physical characteristics from -40 °F up to 248 °F, with a coefficient of thermal expansion close to concrete's, though it does not publish the test temperature range. These figures are each specific to the named product; they should not be read as applying to all epoxies or all urethane cement systems, and this guide has no verified data on tile or grout thermal behavior.
What to put in the written scope:
Food Code 2026's 6-201.13 addresses coved, sealed floor-wall junctures along with drains and graded floors where water-flush cleaning methods are used. Sika lists Ucrete RG29 NA as a cove and detailing mortar at 1/8 to 1/4 inch; ask the contractor how the cove is formed and with which product. Tnemec's Series N222 epoxy mortar is applied at 3/16 to 1/4 inch (minimum 1/8 inch, maximum 1 inch), while Carboline's Shock-Crete HD urethane cement mortar is recommended at 1/4 to 1/2 inch, with a thicker build suggested for more aggressive chemical or thermal conditions.
What to put in the written scope:
Cure schedules differ by product and by jobsite temperature and humidity, and a written schedule should always be confirmed against the current data sheet rather than assumed. Sika's data sheet for Sikafloor-20 NA PurCem urethane cement lists about 18 hours to foot traffic, about 24 hours to light traffic, and about 5 days to full normal traffic, at 68 °F and 50% relative humidity in a 1/4 inch application; the sheet notes that curing times vary with air and substrate temperature and relative humidity.

Facility type and process conditions drive which products a contractor proposes, rather than one system fitting every kitchen. Commercial epoxy flooring more broadly is used across warehouses, manufacturing plants, commercial kitchens, retail showrooms, automotive service centers, and healthcare facilities, where chemical and stain resistance, a seamless non-porous surface, and load-bearing capacity for equipment and forklift traffic are the priorities.
What to put in the written scope:
See the Colorado Commercial Epoxy Flooring contractor hub for how these systems are scoped across facility types.
The Food Code 2026 (6-201.11, 6-201.13) sets expectations for smooth, easily cleanable floors and coved, sealed junctures; Colorado's 6 CCR 1010-2 incorporates the 2022 edition, so confirm the 2022 language with your regulatory authority. Ask your contractor which edition your jurisdiction currently enforces.
Tile systems include grout joints between units, while epoxy and urethane cement cure into a continuous field without joints. This distinction is a structural difference between the systems rather than a guarantee about cleaning outcomes, and any cleanability claim should be checked against the applicable code language and the contractor's written scope.
Service temperature ranges vary by product, and a data sheet should be checked against the kitchen's actual hot-wash and cold-storage conditions. For example, one urethane cement data sheet lists a service range of -40 °F up to 248 °F. Ask the contractor whether the kitchen needs different products in different zones rather than one system everywhere.
The quote should itemize the specific product and manufacturer, installed thickness by area, cove and drain details, cure-time milestones for the jobsite's expected conditions, and the repair process for future damage. It should also note which code edition the local health authority enforces so the design can be checked against it.
Ask each bidder for the written schedule for the specific product, with the temperature and humidity it assumes, and compare it against the product's current data sheet rather than a general figure.
